Preface

This Cisco ANA Customization Guide describes managing soft properties and Threshold Crossing Alarms (TCA). Soft properties enable the user to extend the set of supported properties for each Network Element (NE), by adding soft properties to the Virtual Network Elements (VNEs). These properties extend the Cisco IMO and are available through the client GUI as well as through the BQL API. Soft properties are retrieved from the NE using SNMP, or Telnet/SSH. In addition, alarm thresholding enables the user to constantly monitor selected properties and generate an alarm every time they cross a user-defined threshold or violate a condition.

This guide is intended for use by integrators and any other users who want to manage the soft properties and TCA alarms that are executed within the Cisco Active Network Abstraction (ANA) platform.

It includes the following chapters:

• Chapter 1, “Introducing the Cisco ANA Soft Properties Manager”—Describes the Cisco ANA Soft Properties Manager. In addition, it provides a brief explanation of the terms soft properties and alarm thresholds used throughout this guide.

• Chapter 2, “Getting Started”—Describes the Soft Properties Manager’s working environment and how to access the Soft Properties Manager’s tools. In addition, it describes how to create, edit and delete a soft property.

• Chapter 3, “Examples”—Provides several examples of creating a soft property from start to finish, including defining the TCA alarms and defining a soft property table.

• Appendix A, “Parsing Operators/Rules”—Describes the pre-defined text manipulation operators available for parsing raw device input and turning it into a soft property. In addition, an example of each operator is provided.

• Appendix B, “Alarm Threshold Triggers”—Describes the pre-defined alarm threshold triggers available for defining TCA alarms.

• Appendix C, “Regular Expressions”—Describes the package GNU RegExp containing regular expression consists of a character string, where some characters are given special meaning with regard to pattern matching.

Note Changes to the registry should only be carried out with the support of Cisco Professional Services.

Note Changes to the registry should only be carried out with the support of Cisco Professional Services.

About the Soft Properties ManagerCisco ANA provides deep auto-discovery and maintains a live model of the network. This model is based on Cisco’s Device Component Modeling (DCM) architecture, in which each Network Element (NE) is modeled as an interconnected hierarchy of Device Components (DCs), both physical (for example, cards, ports) and logical (for example, forwarding tables, profiles). Each DC maintains a set of properties, which contain its actual data (status, configuration, performance and so on).

When interacting with Northbound clients, the DCM information is translated internally into Information Model Objects (IMO), this is Cisco’s TMF513-based Northbound information model, which is the public language of the Cisco ANA system with external systems.

The Cisco ANA property management framework enables the user to extend (in runtime) the system’s coverage and capabilities in two areas, namely:

• Soft Properties—Extending the NE data collection and modeling, by adding new properties to the DCs, and assigning them to NE MIB variables. The new soft properties are also automatically added to the Northbound IMO.

• Alarm Thresholds—Assigning various types of alarm conditions to soft properties.

All property definitions and parameters are maintained in XML meta-data in the registry. To ease the definition process, Cisco ANA provides a friendly, simple-to-use GUI that guides the user through the definition and testing process, and hides the underlying XML definitions.

1-1k Abstraction Customization User Guide Version 3.6

Chapter 1 Introducing the Cisco ANA Soft Properties Manager Soft Properties

Soft PropertiesCisco ANA Virtual Network Elements (VNEs) by default model a subset of the device properties, which cover the most important and commonly used properties. Cisco ANA offers the Soft Properties mechanism to enable user-configurable extension of device modeling, which can cover any unsupported MIB variable. This enables adding new monitored NE properties in runtime to the default set of supported properties.

The Soft Properties mechanism enables quick adaptation to new software upgrades and new requirements that arise during ongoing operation and deployment. It provides the field engineer with the ability to adapt the currently installed Cisco ANA software to changes in the deployed network.

Every Soft Property is implemented through a set of definitions that determine how to retrieve, parse and display a certain MIB variable from the NE. The definition process is done through a simple GUI utility, and does not require system restart. Soft properties are retrieved from the NE using SNMP, or Telnet/SSH.

For example, consider the case where the Cisco ANA system monitors the port parameters of an ATM switch, and the operator installs a new software version on the switch that is capable of reporting the BER for each of the ports. Since this capability was not supported in previous software versions of the NE, the Cisco ANA VNE might not support the property. To avoid the need for a new VNE from Cisco, the Soft Property mechanism enables the user to immediately support the new BER feature in the currently installed version.

Alarm ThresholdsCisco ANA’s main positioning is as a mediation layer between the network and the operational and business support systems. As such, it abstracts the physical network and provides a generic, vendor-neutral network model, with a consistent information model and interface.

Cisco ANA also provides the user with the ability to leverage its live network model for intelligent data processing within the mediation layer. This enables Cisco ANA to conduct advanced processing in areas like fault correlation, root-cause analysis, impact analysis, activation design/validation and so forth. This intelligence enables Cisco ANA to provide processed information to the applications in the upper tiers. This enables Cisco ANA to enhance application functionality, while dramatically reducing the application’s complexity and the uploaded data volumes.

Alarm thresholding is one of the major areas in which Cisco ANA can boost its Northbound clients. With this mechanism, Cisco ANA constantly monitors selected properties and generates an alarm every time they cross a user-defined threshold or violate a condition. This eliminates the need for OSS/BSS applications to constantly upload huge amounts of data and process it. Instead, Cisco ANA filters-out irrelevant data, and sends only meaningful notifications.

Basic Concepts and Terms• Managed Element—Anything managed by the system, usually a component managed by the VNE,

for example, a device.

• Network Element (NE)—A user-named physical component or device existing in the network.

Chapter 1 Introducing the Cisco ANA Soft Properties Manager Basic Concepts and Terms

• Virtual Network Element (VNE)—A virtual representation of a single network element as a modeled component. VNEs all communicate with each other to present ANA-based applications with a single, common device abstraction for network element discovery, configuration, status collection, fault analysis and other basic network (FCAPS) functions. VNEs can be extended to support new application functionality.

Chapter 2 Getting Started Opening the Soft Properties Manager

Opening the Soft Properties ManagerThis section provides instructions for launching the Soft Properties Manager. The Soft Properties Manager is launched from a specific network element, which could be a managed element or a selected object within a managed element, such as a port. This network element will be used to develop and test the soft property. The content displayed in the Soft Properties Manager window is based on the location from which it is launched.

Once the soft property has been completed it can be published and attached to a wider scope of managed elements.

Note Initially the soft property only applies to the specific object that you are working on during runtime. Once the soft property has been published and the system has been restarted s it will be applied to all objects all objects of the same type, according to the location to which it is published.

To open the Soft Properties Manager:

Step 1 Right-click on a managed element in the NetworkVision window’s tree pane or workspace to display a shortcut menu.

Creating or Editing a Soft PropertyThe Soft Properties Manager enables the user to create or edit an existing soft property using the Add Soft Property dialog box. First the user must determine the managed element and/or selected object in the network element to which the soft property should be added.

To create a Soft Property

Step 1 Right-click on a managed element in the NetworkVision window’s tree pane or workspace to display a shortcut menu,

or

Open the Inventory window for the required managed element and right-click on the required object in the network element, for example, port or card. A shortcut menu is displayed.


Step 3 Click New Element on the toolbar of the Soft Properties Manager window.

or

Select New Element from the File menu or shortcut menu. The Add Soft Property dialog box is displayed.

The Add Soft Property dialog box is divided into the following tabs (configuration categories):

• General tab enables you to configure general definitions for the soft property. For more information about defining the General parameters see Defining the General Parameters, page 2-9.

• Parsing tab enables you to configure parsing definitions for the soft property. For more information about defining the Parsing parameters see Defining the Parsing Parameters, page 2-11.

• TCA Alarms tab enables you to configure alarm threshold management for the soft property. For more information about defining the TCA Alarms parameters see Defining the TCA Alarms Parameters, page 2-16.

Editing a Soft PropertyThe user can edit an existing soft property and the soft property that is edited will affect only the local instance. When an inherited soft property is edited, the new local instance overrides the generic soft property definition for the specific managed element.

To edit a soft property:

Step 1 Select the soft property that you want to edit in the table of the Soft Properties Manager window.

Step 2 Click Edit Element on the toolbar of the Soft Properties Manager window.

Defining the General ParametersThe General tab enables the user to configure general definitions for the soft property. The user can also configure just a single soft property field or an entire soft property table.

To define the General parameters:

Step 1 Select the General tab in the Add Soft Property dialog box. The General tab is displayed.

The following fields are displayed in the General tab of the Add Soft Property dialog box:

• Name—The soft property identifier, which is unique to the location and IMO scope. This field is mandatory.

Note A warning message is displayed if the name specified already exists. The user will be asked whether to override the existing soft property implementation.

• Label—The soft property name that is displayed in the GUI, which is unique to the location and IMO scope. For tables this is the table name that is displayed in the tab. This field is mandatory.

• Description—A description of the soft property.

The following dropdown lists are displayed in the General tab of the Add Soft Property dialog box:

• Type—The soft property type, namely, Property or Table. By default Property is selected. The fields displayed in the Parsing tab are dependent on the user’s selection.


OL-12510-01

Chapter 2 Getting Started Defining the General Parameters

Note If Table is selected the TCA Alarms tab is not displayed in the Add Soft Property dialog box.

• Polling Rate—The polling rate group to which the soft property is assigned, namely one of the following:

– trapevent

– topo_unicast_pkts

– topo_I2

– buffering

– topo_I1

– configuration

– status

– system

The following checkbox is displayed in the General tab of the Add Soft Property dialog box:

• Enabled—Enables or disables the VNE to run or not run the command. By default this option is enabled.

The following buttons are displayed in the Add Soft Property dialog box:

• OK—Validates the changes according to the field’s rules, namely, the definitions defined in the General, Parsing and TCA Alarms tabs. If the validation is successful, the changes are saved and the Add Soft Property dialog box is closed.

Note A warning message is displayed if the validation is unsuccessful.

• Cancel—Closes the Add Soft Property dialog box without saving any changes.

• Debug—Opens the Debug Soft Property dialog box displaying the status of the soft property debug.

Step 2 Define the soft property’s general parameters.

Note If you selected the soft property type Table proceed to Defining the Parsing Parameters of a Soft Property Table, page 2-14 to continue creating the soft property.

Proceed to Defining the Parsing Parameters, page 2-11 to define the parsing parameters of the soft property.


OL-12510-01

Chapter 2 Getting Started Defining the Parsing Parameters

Defining the Parsing ParametersThe Parsing tab enables the user to configure, view and edit parsing definitions defined for the soft property.

To define the Parsing parameters:

Step 1 Select the Parsing tab in the Add Soft Property dialog box. The Parsing tab is displayed as shown below when the Property type is selected in the General tab.

Note If the Table type is selected in the General tab only the SNMP option is displayed. For more information about defining parsing parameters for a soft property table see Defining the Parsing Parameters of a Soft Property Table, page 2-14.

The Parsing tab enables you to specify either a Telnet/SSH command or a MIB OID for an SNMP GET command.

The following radio buttons are displayed in the Parsing tab:

• Use SNMP get(OID)—The SNMP retrieval expression. The text field is enabled and mandatory when this option is selected. The expression can include environmental arguments.

Note When Use SNMP get(OID) is selected press Ctrl-Spacebar in the text box to open a selection list of the entire collection of parameters available for all the protocols.

An example of the output presented when pressing Ctrl-Spacebar for a port is displayed below.

Figure 2-3 Output

Sometimes, when building a soft property the Telnet/SNMP command is context sensitive. A good example of this is when you want to retrieve some port related data through SNMP, "walk"ing all the ports to find the relevant port each time is not efficient and can greatly affect system performance. To solve this "Instrumentation Data" is available for the soft property. The instrumentation data is a variant between different elements in the system depending on the context object to which you want to add the soft property to.

In this example, the instrumentation data is the port ifIndex. In order to use the ifIndex in the OID, do the following "1.3.1.6......$ifIndex$.5.6.4". In order to ascertain what instrumentation data is available for your context object press Ctrl-Spacebar while the cursor is on the "command" field.

Figure 2-4 Add/Edit Parsing Rule Dialog Box

The Add/Edit Parsing Rule dialog box is used for adding, editing and testing of the parsing operators. Once the required operator is selected, the corresponding arguments are displayed.

The following dropdown lists are displayed in the Add/Edit Parsing Rule dialog box:

• Input Buffer—A dropdown list that displays the list of output arguments defined in previous operators and the default (the standard output buffer of the last predecessor operator that was not redirected into an output argument). This field is mandatory.

The parsing result of operator N is available by default as input for operator N+1 (appear as Default for the Input Buffer). The parsing result of operator N may be directed to a locally defined environment argument. In this case the input for operator N+1 is the same as for operator N. Changing the default input buffer is supported by selecting an input buffer other than Default. The available inputs buffers for Operator N+1 are the set of output arguments defined in Operators 1 through N.

The fields displayed in the Expression area of the window change depending on your selection in the Operator dropdown list, which is mandatory. When an operator is selected the corresponding arguments are displayed. The Operator dropdown list enables you to select one of the available parsing operators, namely:

• Header And Footer—Removes a specified number of lines from the header and footer of the input text. For more information see Header and Footer, page A-2.

• Remove Lines—Removes a range of lines from the specified starting row to the specified end row of the input text. For more information see Remove Lines, page A-3.

1 Argument 1

2 Argument n

3 Source

4 Result


OL-12510-01


• Select Lines—Extracts a range of lines from the specified starting row to the specified end row of the input text. For more information see Select Lines, page A-4.

• Replace—Finds one or all occurrences of a substring, which matches a specified regular expression, and replaces it with a specified value. For more information see Replace, page A-5.

• Match—Finds and extracts a substring, which matches a specified regular expression. If no match can be found the output buffer receives an empty string. For more information see Match, page A-6.

• Set—Formats the input buffer and local arguments defined in previous operators using a regular expression. For more information see Set, page A-7.

• Substring—Extracts a substring of a specified length from a specified starting point. For more information see Substring, page A-8.

• Parse Integer—Uses the substring rule and when a result is received with the substring it converts it into an integer value. For more information see Parse Integer, page A-9.

Note If the substring operator contains any characters the parsing integer operator will fail.

The Argument 1 and Argument n fields displayed in the Add/Edit Parsing Rule dialog box is dynamic and lists the corresponding arguments according to the selected operator. For more information about the operators and the corresponding arguments that are displayed see Appendix A, “Parsing Operators/Rules”.

The Direct result to output buffer variable checkbox and corresponding field enables you to direct the parsing output to the provided argument instead of it being the input value for the next operator. The text box is only enabled when the checkbox is selected and a unique (within the complete parsing sequence of this soft property instance) argument name must be provided in this field.

The Simulation area is divided into two text areas:

• The Source text box is used to enter or paste parsing information.

• The Result text box is used to view the parsed result.

The information entered and displayed in the Simulation area is not saved when the dialog box is closed. The Test Expression button parses the information entered in the Source text box according to the parsing operator defined and displays the result in the Result text box.

Step 2 Click in the top right corner to close the Inventory window.


OL-12510-01

Chapter 2 Getting Started Publishing the Soft Property

Proceed to Publishing the Soft Property, page 2-20 to publish the soft property.

Publishing the Soft PropertyA property definition is applicable to all objects of the same type in the selected NE. However, the user may want to apply the same property definitions to all NEs of the same type or family. This requires moving the property definition from the specific NE instance to a higher level in the registry hierarchy.

After the soft property has been defined and tested on a specific instance of a managed element it can be published and applied to wider scope of managed elements in the network.

The Soft Properties Manager Soft Properties Publish Controller dialog box enables the user to publish the soft property to one or more locations across the inheritance hierarchy (as defined in the system). In other words the user defines the scope where the soft property will be applied in the hierarchy.

Different variations of a soft property can be used for different managed elements and network elements, where the implementation of the soft property is different for each managed element or network element.

An example of an inheritance hierarchy is displayed below. In this example, the top level of the hierarchy is All devices and the lowest level of the hierarchy is Device XYZ.

Figure 2-6 Inheritance Hierarchy Example

When a soft property is published to a node in the hierarchy, this overrides any inherited soft properties from a higher level, and automatically applies it to all its children. For example, if a soft property is published to Cisco 7200 it will override any variant of this soft property which is defined at a higher level, and will be assigned to all devices of type Cisco 7200 in the system.

Note It is highly recommended that you measure the affect of publishing the soft property on memory usage of the system before it is published. To view the changes you must restart the VNE or unit in order for the publishing to take affect. For more information about measuring the affect of publishing the soft property, please contact Cisco Professional Services.

Note Soft property publishing sometimes deeply affects the system memory usage, device utilization and system performance. For example, the user can add a property running "show running-config" to the device in status polling and publish it to a group of devices. This will probably cause the system memory usage to jump and the device’s utilizations to jump.

P P E N D I X B Alarm Threshold Triggers
This chapter describes the pre-defined alarm threshold triggers available for defining TCA alarms that are displayed in the Trigger tab of the Add TCA dialog box. For each alarm threshold trigger its name, description, and the unique fields displayed in the dialog box are described.

The user can define multiple alarms for the same soft property. The alarm is displayed in the ticket pane of the NetworkVision window.

A counter value, as described in this chapter, is a numeric value that always increases.

For more information about the Add TCA dialog box see Defining the TCA Alarms Parameters, page 2-16.

• Value Equal, page B-1—Describes the Value Equal threshold type.

• Value Not Equal, page B-2—Describes the Value Not Equal threshold type.

• Upper Threshold, page B-2—Describes the Upper Threshold type.

• Lower Threshold, page B-3—Describes the Lower Threshold type.

• Upper Rate, page B-4—Describes the Upper Rate threshold type.

• Lower Rate, page B-5—Describes the Lower Rate threshold type.

Value EqualThe alarm condition is reached when the soft property value is equal to the value defined in the “Alarm Value” regardless if it is numeric or not.

When the Value Equal threshold type is selected from the Trigger dropdown list of the Add TCA dialog box the Trigger tab is displayed.

The following fields are displayed in the Trigger tab when the Value Equal threshold type is selected:

• To value—The target value.

• Trigger alarm only if change persists more than—Select this option to trigger the alarm if the alarm criteria persist for the defined period. The time period is defined in milliseconds in the trigger alarm field. For example, if CPU usage is over 85% (the alarm criteria) and this persists for more than one minute (the defined period), then the alarm is triggered. Considering that the soft property polls the device every x seconds, if the defined period is less than x, this will be meaningless.

B-1action Customization User Guide Version 3.6

Appendix B Alarm Threshold Triggers Value Not Equal

Value Not EqualThe alarm condition is reached when the soft property value is NOT equal to the value defined in the “Alarm Value” regardless if it is numeric or not.

When the Value Not Equal threshold type is selected from the Trigger dropdown list of the Add TCA dialog box the Trigger tab is displayed as follows:

Figure B-1 Trigger Tab - Value Not Equal

The following fields are displayed in the Trigger tab when the Value Not Equal threshold type is selected:

• To value—The target value.

• Trigger alarm only if change persists more than—Select this option to trigger the alarm if the alarm criteria persist for the defined period. The time period is defined in milliseconds in the trigger alarm field.

Upper ThresholdThe upper threshold value, which when crossed triggers the alarm for the defined numeric properties.

This threshold trigger must receive a numeric value. In order to receive a numeric value the parse integer rule must be applied on the soft property as an ending rule. For more information about parsing integers see Appendix A, “Parsing Operators/Rules”.

B-2Cisco Active Network Abstraction Customization User Guide Version 3.6

OL-12510-01

Appendix B Alarm Threshold Triggers Lower Threshold

When the Upper Threshold type is selected from the Trigger dropdown list of the Add TCA dialog box the Trigger tab is displayed as follows:

Figure B-2 Trigger Tab - Upper Threshold

The following fields are displayed in the Trigger tab when the Upper Threshold type is selected:

• Trigger alarm when value is above—The value which when crossed generates the alarm.

• Clear alarm when value is below—The value which when crossed (when going back) clears the alarm.


Lower ThresholdThe lower threshold value, which when crossed triggers the alarm for the defined numeric properties.



OL-12510-01

Appendix B Alarm Threshold Triggers Upper Rate

When the Lower Threshold type is selected from the Trigger dropdown list of the Add TCA dialog box the Trigger tab is displayed as follows:

Figure B-3 Trigger Tab - Lower Threshold

The following fields are displayed in the Trigger tab when the Lower Threshold type is selected:

• Trigger alarm when value is below—The value which when crossed generates the alarm.

• Clear alarm when value is above—The value which when crossed (when going back) clears the alarm.


Upper RateThe upper rate trigger is used for checking the counter value changes over a period of one second. When the specified rate is crossed it triggers the alarm for the defined numeric property. When this is used together with the Trigger alarm only if change persists more than option, described in Upper Threshold, page B-2, you can check that the rate is maintained above the specified value over time.

Note The calculation for the "rate every one second" is as follows, if the property is sampled every x seconds the calculation will be the current value less the previous value divided by x seconds.



OL-12510-01

Appendix B Alarm Threshold Triggers Lower Rate

When the Upper Rate threshold type is selected from the Trigger dropdown list of the Add TCA dialog box the Trigger tab is displayed as follows:

Figure B-4 Trigger Tab - Upper Rate

The following fields are displayed in the Trigger tab when the Upper Rate threshold type is selected:

• Trigger alarm when value is above—The value which when crossed generates the alarm.

• Clear alarm when value is below—The value which when crossed (when going back) clears the alarm.


Lower RateThe lower rate trigger is used for checking the counter value changes over a period of one second. When the specified rate is crossed it triggers the alarm for the defined numeric property. When this is used together with the Trigger alarm only if change persists more than option, described in Upper Threshold, page B-2, you can check that the rate is maintained below the specified value over time.

Note The calculation for the "rate every one second" is as follows, if the property is sampled every x seconds the calculation will be the current value less the previous value divided by x seconds.

A
P P E N D I X C Regular Expressions
This section is based on the documentation of the package GNU RegExp.

A regular expression consists of a character string where some characters are given special meaning with regard to pattern matching. Regular expressions have been in use from the early days of computing, and provide a powerful and efficient way to parse, interpret and search and replace text within an application.

Supported SyntaxWithin a regular expression, the following characters have special meaning:

Positional Operators^ matches at the beginning of a line1

$ matches at the end of a line2

\A matches the start of the entire string

\Z matches the end of the entire string

\b matches at a word break (Perl5 syntax only)

\B matches at a non-word break (opposite of \b) (Perl5 syntax only)

\< matches at the start of a word (egrep syntax only)

\> matches at the end of a word (egrep syntax only)

One-Character Operators. matches any single character

\d matches any decimal digit

\D matches any non-digit

\n matches a newline character

\r matches a return character

\s matches any whitespace character

\S matches any non-whitespace character

C-1action Customization User Guide Version 3.6

Appendix C Regular Expressions Supported Syntax

\t matches a horizontal tab character

\w matches any word (alphanumeric) character

\W matches any non-word (alphanumeric) character

\x matches the character x, if x is not one of the above listed escape sequences.

Character Class Operator[abc] matches any character in the set a, b or c

[^abc] matches any character not in the set a, b or c

[a-z] matches any character in the range a to z, inclusive

A leading or trailing dash will be interpreted literally.

Within a character class expression, the following sequences have special meaning if the syntax bit RE_CHAR_CLASSES is on:

[:alnum:] Any alphanumeric character

[:alpha:] Any alphabetical character

[:blank:] A space or horizontal tab

[:cntrl:] A control character

[:digit:] A decimal digit

[:graph:] A non-space, non-control character

[:lower:] A lowercase letter

[:print:] Same as graph, but also space and tab

[:punct:] A punctuation character

[:space:] Any whitespace character, including newline and return

[:upper:] An uppercase letter

[:xdigit:] A valid hexadecimal digit

Subexpressions and Backreferences

(abc) matches whatever the expression abc would match, and saves it as a subexpression. Also used for grouping.

(?:...) pure grouping operator, does not save contents

(?#...) embedded comment, ignored by engine

\n where 0 < n < 10, matches the same thing the nth subexpression matched.

Branching (Alternation) Operatora|b matches whatever the expression a would match, or whatever the expression b would match.

C-2Cisco Active Network Abstraction Customization User Guide Version 3.6

OL-12510-01

Appendix C Regular Expressions Unsupported Syntax

Repeating OperatorsThese symbols operate on the previous atomic expression.

? matches the preceding expression or the null string

* matches the null string or any number of repetitions of the preceding expression

+ matches one or more repetitions of the preceding expression

{m} matches exactly m repetitions of the one-character expression

{m,n} matches between m and n repetitions of the preceding expression, inclusive

{m,} matches m or more repetitions of the preceding expression

Stingy (Minimal) MatchingIf a repeating operator (above) is immediately followed by a ?, the repeating operator will stop at the smallest number of repetitions that can complete the rest of the match.

LookaheadLookahead refers to the ability to match part of an expression without consuming any of the input text. There are two variations to this:

(?=foo) matches at any position where foo would match, but does not consume any characters of the input.

(?!foo) matches at any position where foo would not match, but does not consume any characters of the input.

Unsupported SyntaxSome flavors of regular expression utilities support additional escape sequences, and this is not meant to be an exhaustive list. In the future, gnu.regexp may support some or all of the following:

(?mods) inlined compilation/execution modifiers (Perl5)

\G end of previous match (Perl5)

[.symbol.] collating symbol in class expression (POSIX)

[=class=] equivalence class in class expression (POSIX)

s/foo/bar/ style expressions as in sed and awk (note: these can be accomplished through other means in the API).
